[0033] Example 2:

[0034] The post-processing and polishing equipment for the 3D printed product provided in Example 1 has been further optimized, specifically, as follows: Figure 1-2As shown, in order to facilitate the wiring and electrical connection of the first motor 11 mounted inside the inner cylinder 7, the second motor 24 mounted inside the switching support plate 8, the control module 5, and the power supply module 6, wire holes are provided inside the inner cylinder 7 and the switching support plate 8, and wire tubes are provided inside the body support cylinder 1 and the top seat 2.

[0035] The post-processing polishing equipment for 3D printed products provided by this utility model is used as follows: When using this equipment while holding the main control handle 3 and the auxiliary handle 4, the second motor 24 is started to drive the second bevel gear 25 to rotate. The meshing of the second bevel gear 25 with the two first bevel gears 23 drives the two transmission shafts 21 and the fourth flat gear 22 to rotate. In conjunction with the meshing of the fourth flat gear 22 with the third flat gear 20, the first rotating shaft 16 and the second rotating shaft 18 are driven to rotate, which in turn drives the conical grinding head 17 and the universal grinding disc 19 to rotate, thereby using the conical grinding head 17 or the universal grinding disc 19 to polish the product.

[0036] When it is necessary to perform overall or detailed polishing on the product, and thus switch between the conical grinding head 17 and the universal grinding disc 19, the first motor 11 is started to drive the second spur gear 12 to rotate. The meshing of the second spur gear 12 with the first spur gear 10 drives the support shaft 9 and the switching support disc 8 to rotate, thereby changing the position of the conical grinding head 17 and the universal grinding disc 19, thus achieving function switching without the need for additional sandpaper, effectively ensuring polishing efficiency.
